Optimisation of Maintenance Work at a Hydroelectric Power Plant

The first part of the diploma thesis presents the basic classification of maintenance work with an emphasis on maintenance work for mechanical equipment and assemblies that I perform as a mechanical maintenance technician at a hydroelectric power plant. Most of the work described is similar for all hydroelectric power plants where I have also participated in maintenance work myself. The second part focuses on the optimisation and execution of daily, weekly and monthly maintenance work, inspection, overhaul and extended overhaul. The procedures or work are presented ** from the insertion of auxiliary gates to final tests and measurements,** in short, everything that should be inspected, repaired, replaced and tested during maintenance at hydroelectric power plants, so that unexpected downtime does not occur later during operation. The work is ** evaluated** and ** graphically displayed** according to the start, duration and completion of the work.

Problem

The first part of the diploma thesis presents the basic classification of maintenance work with an emphasis on maintenance work for mechanical equipment and assemblies that I perform as a mechanical maintenance technician at a hydroelectric power plant. Most of the work described is similar for all hydroelectric power plants where I have also participated in maintenance work myself. However, some work is different and varies depending on the facility or improved technology of the installed mechanical equipment in relation to the time of renovation.

Solution and Method

The second part focuses on the optimisation and execution of daily, weekly and monthly maintenance work, inspection, overhaul and extended overhaul.

Results

The procedures or work are presented from the insertion of auxiliary gates to final tests and measurements, in short, everything that should be inspected, repaired, replaced and tested during maintenance at hydroelectric power plants, so that unexpected downtime does not occur later during operation. The work is ** evaluated** and ** graphically displayed** according to the start, duration and completion of the work. The work must be carried out with quality so that there are no subsequent failures on the equipment on which maintenance work and inspections have been performed. ** Through regular annual maintenance work** we contribute to better operational capability – availability of the unit in the production of electrical energy.

In this way, we avoid increased costs and economic damage due to unpredictable downtime, whilst extending the operational lifespan of machinery and equipment.
